How many grams of water are produced when 2.5 mil oxygen reacts with hydrogen?
When 2.5 moles of oxygen react with hydrogen, they react in a 1:2 ratio to produce water. Therefore, 2.5 moles of oxygen will produce 5 moles of water. To convert moles to grams, you'll need to know the molar mass of water, which is approximately 18 grams/mol. So, 2.5 moles of oxygen will produce 90 grams (5 moles x 18 grams/mole) of water.
What is pounds for 90 grams?
90 grams is about 0.2 (0.198416) pounds.
How many grams of NaCl can be dissolved in 100g of water at 90 degrees Celsius?
7
What would you convert 90kg to g?
To convert 90 kg to grams, you would multiply 90 by 1000 (since there are 1000 grams in one kilogram), resulting in 90,000 grams.
How many grams are in 90 milligrams?
There are 1000 milligrams in a gram. To convert, you divide by 1000. 90/1000 is 0.09 grams.
How much Na Cl will dissolve in 350 g of water at 90 degrees Celsius?
The answer is 134,645 grams of NaCl.
How many grams of water can be prepared from 5moles of hydrogen at standard conditions?
At standard conditions, 1 mole of hydrogen reacts with 0.5 moles of oxygen to form 1 mole of water. Therefore, to form 5 moles of water, you will need 5 moles of hydrogen and 2.5 moles of oxygen. The molar mass of water is approximately 18 g/mol, so 5 moles of water would weigh 90 grams.
How many moles of 5grams of oxalic acid?
To calculate the number of moles in 5 grams of oxalic acid (C2H2O4), first determine the molar mass of oxalic acid, which is 90.03 g/mol. Then, divide the mass (5 grams) by the molar mass to get the number of moles. In this case, 5 grams is equal to approximately 0.055 moles of oxalic acid.
How many kilograms are in 90 grams?
90 kg = 90 000 gTo convert from kg to g, multiply by 1000.
How many atoms are in 45 grams of pb?
First of all we convert the mass of leadto moles. Using the equation moles = mass(g) / Ar (Realtive atomic Mass)_. Mass( g) = 45 g Ar =~ 207 (Periodic Table). Hence moles(Pb) = 45 x 207 Moles (Pb) = 9315 moles. Next using the Avogadro number. 1 moles(of A SUBSTANCE) contains 6.022 x 10^(23) atoms. Hence number of atoms in 9315 moles = 9315 x 6.022 x 10^(23) = 5.61 x 10^(27) atoms. As a 'silly' number. 5,610,000,000,000,000,000,000,000,000 atoms.
How many moles are in 9.8 grams of Calcium?
To find the number of moles in 9.8 grams of Calcium, you first need to calculate the molar mass of Calcium, which is about 40.08 g/mol. Then, divide the given mass by the molar mass: ( \frac{9.8 , \text{g}}{40.08 , \text{g/mol}} \approx 0.245 , \text{moles})
